We can remove the load commands if we don't need to upgrade the firmware.

Configure cnf file location to flash

• The cnf file will be created in this location.
• Also when configuring the load commands, it will look for the firmware file in this location
  • If the firmware is in the root of flash, the tftp binding will also be created automatically.
• If you set the cnf location to flash but the sccp firmware is not located in the root directory, it will take a lot longer to create the cnf files.

Load firmware

• Case sensitive
• If no phone load is specified, the current phone load of the phone is used
• In Cisco Unified CME 7.0/4.3 and earlier versions, do not use the file suffix (.bin, .sbin, .loads) for any phone type except the Cisco ATA and Cisco Unified IP Phone 7905 and 7912.
• In Cisco Unified CME 7.0(1) and later versions, you must use the complete filename, including the file suffix, for phone firmware versions later than version 8-2-2 for all phone types

• Required for Cisco Unified CME 7.0/4.3 and earlier versions
• Cisco Unified CME 7.0(1) and later versions:
  • Required only if the location for cnf files is not flash or slot 0.
  • Use the complete filename, including the file suffix, for phone firmware versions later than version 8-2-2 for all phone types.
  • Make sure the cnf-file location parameter is set
• Configure TFTP firmware download
